I've had that mold for years and it's a good one for basic panfishing, but I honestly can't say it has any special action to it. It will "slide" and can be skipped fairly easily, depending on how it's dressed.
I like it because it tends to fall flatter than a round head jig, but otherwise all that lead does is add weight for casting & sinking.
I have the Larva jig too.
These are typically how I dress them.
